' Application December 26, 1929 Serial No. 16,437

1 Claim. (Cl. 112261) My said invention relates to sewing machine guards and more specifically to a guard intended for use with twoneedle hemstitching machines h of the type illustrated in the patent to Card No.

a 1,526,459. Certain parts of this machine are exposed in such a position as to be near the work,

including rotary shafts lubricated from outside 7 oil cups and the excess oil is liable to drip on the V work or to be thrown off by the rotating'shafts 10- and so come in contact with the work. There is also danger that the Work may contact with the shafts and so become soiled or become entangled in the moving parts of the machine and it is an object of my invention to provide a guard with means for preventing such entanglement, soiling or spattering of oil.

Another object of the invention is to provide a guard for the needles and presser foot, which from these parts. In ordinary practice it is necessary for the operative to hold the work with one hand in front of the needles and presser foot and with the other hand at the rear of these parts. By the use of a shield or guard at therear of the needles and presser foot the work is kept from rolling back against the machine head and thus requires less attention from the operator, who may remove her hand from the work at the N rear side of the presser foot at certain times without any danger that the work will roll back against the head of the machine and thus become soiled or entan led with movin arts of the g g p N Fig. 4: I have indicated how the upwardly exmachine. i

It may be noted also as to that part of my guard first referred to that this prevents the oil from being splashed on the arm of the operator,

which is objectionable from the standpoint of personal cleanliness and also because it may be transferred thence to the work or to other objects.

Referring tothe drawing, which is made a part of this application and in which similar reference characters indicate similar parts,

1 Fig. 1 is a rear elevation of a sewing machine with my guard applied thereto,

Fig. 2 an end elevation, V

Fig. 3 a section on line 3-3 of Fig. 1, and

Fig. 4 a plan of a part of the guard.

In the drawing, reference character 10 indicates generally a head of a sewing machine having a projecting arm 11.. A pulley 12 at one end of the machine is connected to working instrumentalities such as one or more needles 13 at the other end, one or more piercers l4, cutter blades (not shown), etc., by means of shafts, and gearing carried by the arm 11, one such shaft being indicated at 15. The shaft '15 is a rock- I shaft for operating a piercer bar and a cutting blade as in the Card patent above referred to. Open oil cups for such shaft are indicated at 16. The presser foot is shown at 17.

My guard comprises a part 18 lying underneath the arm 11 and bent up at the rear side, asindicated in Fig. 1, approximately to the level of shaft 15. This part maybe made of any suitable material which will hold its form, such as sheet metal, and it isbent downward adjacent the head as indicated at ,19 so as to support the guard in position. It will be seen that this part of the guard extends substantially under the whole arm and at least sufliciently so to prevent any oil from dripping on the work and to prevent engagement of the work with the moving parts in the arm.

guard will serve to guide thecompleted workawa'y, l Qthel principal p Of y guard 0 prises two substantially upright pieces 20 and 21 which preferably are formed from a single length of 'wire and which embrace the downwardly extending portion of the casing of the arm. Adjacent the lower end of members 20 and 21 I provide a number of bowed wires 22 forming a sort of basket-like shield at the rear side of the operating elements of the machine. It will be seen that this shield is wider than the space occupied by these operating elements and as the completed work passes underneath the shield it will be prevented from curling back under oragainst. the adjacent parts of the machine. In

tending members 20 and 21 are connected at the upper forward ends by a limb 23. From this oil guard, such aperture serving to receive a screw which normally holds other parts of the machine and which I use for additionally sup porting my device. It will be obvious that such an aperture could also receive a screw tapped into the fixed casing of the arm.

It will be obvious to those skilled in the art that various other modifications may be made in my device without departing from the spirit of my invention and therefore I do not limit myself to what is shown in the drawing and described in the specification but only as set forth in the appended claim.

It will also be obvious that the work at the back of the needles will require but little attention from the operator, as there is little or no danger of the work becoming entangled in the moving parts and therefore greater concentration can be had on that part of the work at the front of the machine, so increasing the production of the machine.

Usually machines of this character are equipped with a light at the front so constructed as to act as a spotlight on the presser foot where the needle (or needles) pass through the work. In addition to its function of controlling the work and preventing the work from being spotted by oil it is within the province of my invention to construct the guard in such a manner as to reflect the needle light on the moving parts adjacent the presser foot. This can be done by making the guard of suitable material for the purpose or by painting it a light reflecting color such as white.

said first-named part and extending downward- 1y therefrom to the rear of the working instrumentalities to guide the work away from them, and means for supporting the guard on said arm of the machine, substantially as set forth.

JULIA POWELL.
